Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Example 1
Fig. 1 is a flowchart illustrating a multimedia asset cover presentation method according to an exemplary embodiment. The method can be applied to a server. As shown in fig. 1, a method for displaying a cover of a multimedia resource according to an embodiment of the present disclosure includes:
in step S11, behavior data of the user for the first multimedia resource is acquired;
in step S12, a mapping pair between a first cover of the first multimedia asset and a first tag associated with the first cover is established based on the behavior data.
For example, when a user browses a video through a video-like application, user interaction behavior data in a user request may be obtained, where the user behavior data may include interaction behaviors of the user for searching, clicking, playing, or commenting on a first multimedia resource (e.g., a video), and behavior data corresponding to occurrence times of the interaction behaviors. Wherein the first multimedia asset can be a video asset with user behavior, the first multimedia assetThe set of sources P may be denoted as P ═ v1，v2，…，vMIn which v is1，v2，…，vMA first multimedia resource may be represented, M representing the number of first multimedia resources, M being greater than 1.
In one possible implementation, the behavior data may include: and the user behaviors of the user aiming at the first multimedia resource in the specified time and the corresponding user behavior quantity. The specified time may be a preset time, and for example, the specified time may be set to 30 days. Behavior data that is more distant from the current time than the specified time may be disregarded, thereby reducing the system burden. The present disclosure is not limited to specific settings for the designated time.
In one possible implementation, the user behavior may include one or more of a click, play, comment, search for the first multimedia asset. The present disclosure is not limited to a particular type of user behavior.
In one possible implementation, a mapping pair between a first cover of a first multimedia asset and a first tag associated with the first cover may be established based on behavioral data of a user. The first cover can be a cover adopted by a first multimedia resource when a user generates user behavior aiming at the first multimedia resource; the first label may be a label corresponding to the first cover. For example, if the first multimedia resource that the user clicks to play (generate the user behavior) is a certain action video, the first cover is a cover picture that the application presents to the user when the user views the action video, the first tag is a tag corresponding to the tendency of the cover picture, such as "action", or a tag of a person in the cover picture, such as "lie XX".
In one possible implementation, the mapping pair between the first cover and the first label may be represented as tm＝f(Vm) Wherein V ismRepresenting a first multimedia asset vmFirst cover of (v)mBelong to the set P ({ v)1，v2，…，vM}) M has a value in the range of 1 to M; f represents a mapping function; t is tmThe representation corresponds to a first cover VmThe first tag of (1). Thus, there may be a first set of tags T ═ { f (V)1)，f(V2)，…，f(VM)}. Wherein each first cover may be manually labeled with a first label, the first label corresponding to the first cover may be determined by dictionary lookup to determine a mapping pair between the first cover and the first label.
Determining a relevance of a second cover of a second multimedia asset to the user based on the mapping pair, the second cover of the second multimedia asset to be presented to the user, and a second tag associated with the second cover in step S13;
in step S14, a second cover is presented to the user according to the relevance.
Fig. 2 is a flowchart illustrating a step S13 of a multimedia asset cover presentation method according to an exemplary embodiment. As shown in fig. 2, in one possible implementation, step S13 includes:
in step S131, determining a first relevance of the second label to the user based on the mapping pair;
in step S132, determining a second degree of association of a second cover with respect to a second tag based on the second cover and the second tag;
in step S133, a relevance of the second cover for the user is determined based on the first relevance and the second relevance.
For example, based on the mapping pairs representing the interest tendency of the user, the relevance of one or more second covers of a second multimedia resource (e.g., a video resource) to be presented to the user can be obtained, so that the covers meeting the interest of the user are selected from the second covers to be presented to the user. The second multimedia resource can be a video resource to be displayed to the user in the interface of the video application; the second cover can be one or more covers of the second multimedia resource, and can be a cover picture which is edited, intercepted or customized by a user; the second label may be one or more labels associated with the second cover, for example, the second label may include a label corresponding to a propensity of the second cover, such as "action," and/or a label of a character in the second cover, such as "lie XX," and the like.
In one possible implementation manner, in step S131, based on the mapping pair between the first cover and the first tag, a first relevance of the second tag to the user may be obtained.
Fig. 3 is a flowchart illustrating a step S131 of a multimedia asset cover presentation method according to an exemplary embodiment. As shown in fig. 3, in one possible implementation, step S131 includes:
step 1311, determining user behaviors of the user for the first cover with the second label and time of the user behaviors from the current moment based on the mapping pairs;
step S1312, attenuating the weight of the user behavior based on the time of the user behavior from the current moment, and determining the short-term weight of the user behavior;
step S1313, determining a first relevance of the second label for the user based on the user behavior and the short-term weight.
For example, for a second label associated with a second cover, a mapping pair (t) between the first cover and the first label may bem＝f(Vm) If there is a first tag identical to the second tag, a first cover page associated with the first tag may be obtained, and a user behavior of the user for the first cover page, such as clicking, playing, etc., and a time from the user behavior to the current time may be determined.
In one possible implementation, the short-term weight of the user behavior may be determined by attenuating the weight of the user behavior based on the time of the user behavior from the current time. The weight attenuation of the user behavior with longer time from the current moment is considered to be larger, and the short-term weight of the user behavior is considered to be lower; conversely, the weight attenuation of the user behavior with shorter time from the current moment is smaller, and the short-term weight of the user behavior is higher. Based on the user behavior and the short-term weight of the user behavior, a first relevance of the second label to the user may be determined.
In a possible implementation, if the second multimedia asset to be presented to the user has N second covers (of which the ith second cover may be denoted as p)iI takes a value of 1-N); and a second cover piHaving n second tags (wherein the k second tag can be denoted as t)kAnd k takes the value of 1-n), the first correlation can be obtained by using the following formula (1):
in the formula (1), h (t)k) Can represent a second tag tkA first degree of correlation for the user; w (q)j) Can represent the user as having a second label tkOf the jth first cover qjThe number of user actions; h (q)j) Can represent that the user aims at the jth first cover qjThe user behavior is away from the time of the current moment; decade may denote the attenuation coefficient.
In one possible implementation, escapeH(qj)The number of user actions w (q) can be representedj) The attenuation coefficient decay may be smaller than 1, for example, the decay may be 0.5-0.95, for example, the decay may be 0.9. As can be seen, the longer the user behavior is from the current time, the smaller the short-term weight item is, the lower the first relevance of the second tag to the user is; conversely, the shorter the time from the user behavior to the current moment, the larger the short-term weight item is, the higher the first relevance of the second tag to the user is.
In one possible implementation, the tag may have a second tag tkAll the first covers q ofjWeighted sum of user behavior
And log the summation result to perform time attenuation, so as to obtain a second label tkFirst degree of correlation h (t) for a userk). Having a second tag t in the user pairkWhen the behavior frequency of the video resource is too much, the frequency attenuation can avoid the overlarge data fluctuation, so that the first correlation degree h (t)k) The data of (2) is smoother.
In this way, a first degree of relevance of the second tag to the user may be obtained.
In one possible implementation manner, in step S132, based on the second cover and the second tag, a second degree of correlation of the second cover to the second tag may be determined.
For example, for a different second tag, the relevance to the second cover may be different, e.g., for tags of people in the second cover (e.g., "lie XX" and "X"), it may be that "lie XX" appears more frequently in the second multimedia resource, and the relevance to the second cover is higher; and the fewer occurrences of "X" the less relevant the label is to the second cover.
In one possible implementation, the second degree of correlation may be obtained by using the following equation (2):
in the formula (2), g (p)i,tk) Can represent a second cover piFor the second label tkA second degree of correlation; click (p)i) Can represent a plurality of users aiming at having a second label tkSecond cover piThe number of actions of (c);
can represent a plurality of users aiming at having a second label tkAll behavior numbers of all second covers.
For example, multiple second cover sheets of a second multimedia asset may correspond to the same second tag tkMultiple users are directed to having a second label tkSecond cover piBehavior ofThe number of users is a second label tkThe larger the proportion of all the behavior numbers of all the second covers is, the second cover p can be considered to beiFor the second label tkSecond degree of correlation g (p)i,tk) The higher.
In this way, a second degree of correlation of the second cover to the second label may be obtained.
In one possible implementation, based on the first correlation h (t)k) And a second degree of correlation g (p)i,tk) The second cover p can be determinediRelevance to user S (p)i)。
In one possible implementation, the second cover p may be determined using the following equation (3)iRelevance for the user:
in the formula (3), S (p)i) An ith second cover p representing a second multimedia assetiRelevance for the user; h (t)k) Representing a second cover piOf the kth second tag tkFor a first degree of relevance to the user, n represents a second cover piThe number of the second tags, k is in the range of 1-n; g (p)i,tk) Representing a second cover piFor the second label tkA second degree of correlation; w (q)j) Representing user to have a second label tkOf the jth first cover qjThe number of user actions; h (q)j) Indicating that the user is directed to the jth first cover qjThe user behavior is away from the time of the current moment; decapay represents the attenuation coefficient; click (p)i) Representing multiple users against having a second label tkSecond cover piThe number of actions of (c);
representing multiple users against having a second label tkAll the second covers piAll of the number of actions.
For example, a second tag t may be obtainedkFirst degree of correlation h (t) for a userk) And a second cover piFor the second label tkSecond degree of correlation g (p)i,tk) And then all the second labels t with the value range of 1 to n are comparedkSumming to obtain the second cover piRelevance for the user.
In one possible implementation, the relevance of all second covers of the second multimedia asset to the user may be determined in the manner described above. And, the relevancy may be ranked, and the second cover with the highest relevancy may be considered as the cover in which the user is most interested, and the second cover may be presented to the user at the front end.
According to the embodiment of the disclosure, a mapping pair between a cover and a label can be established according to behavior data of a user for multimedia resources, the correlation between the user and a video cover is calculated, the correlation of the cover of the multimedia resources to be displayed to the user for the user is determined, the video cover is subjected to personalized sequencing, and the cover is displayed to the user according to the correlation, so that the displayed video cover is matched with the interest of the user, thousands of people are achieved, and the matching degree of the user and rich information of videos is improved; and the video covers can be sorted in real time, the behavior data of the user can be fed back in real time, and the user experience is improved.
Table 1 is a diagram illustrating an application scenario of a multimedia asset cover presentation method according to an exemplary embodiment.
As shown in table 1, in this exemplary application scenario, the second multimedia asset to be presented to the user may have a second cover P1 (click volume click of multiple users is 200), P2 (click volume click of multiple users is 100), P3 (click volume click of multiple users is 50), and a second cover P1 may have second tags t1, t 2; second cover P2 may have second tabs t2, t 3; second cover P3 may have second tabs t1, t3, and the second degree of association of second cover P1 with respect to second tab t1 may be that the number of clicks of multiple users for second cover P1 with second tab t 1/the number of clicks of multiple users for all second covers with second tab t1 (200+50) ═ 0.8; likewise, the second degree of association of the second cover P1 for the second tag t2 may be (200)/(200+100) ═ 0.67.

In the same manner, a correlation of the second cover P2 for the user of 0.43 can be obtained; the relevance of the second cover P3 to the user is 0.25.
